Some planets may be more habitable than EarthEarth doesn't have to be the best planet in the universe.
Two dozen planets outside our Solar System are already known to have conditions more suited for life. Potential "
super habitable" planets could be much older, slightly larger, slightly warmer, and possibly wetter than Earth. All 24 of the top "
superhabitable" contenders are more than 100 light-years away.
But habitability doesn't mean these planets definitely have life on them,
they're just conditions conducive to life.
